Fermentation of a Carbohydrate: Ethanol from Sucrose Abstract The purpose of this lab was to demonstrate the fermentation process of ethanol from the substrate sucrose. To make ethanol from sucrose two enzymes invertase and zymase were used. Vacuum filtration and fractional distillation were performed to get a more concentrated solution. The density of ethanol was .825 g/mL with a percent composition of 85% pure

making‚ or vinification‚ is the production of wine‚ starting with selection of the grapes or other produce and ending with bottling the finished wine. Although most wine is made from grapes‚ it may also be made from other fruit or non-toxic plant material. The basic fermentation process whereby alcohol is produced from the sugar in grapes is very simple‚ but its chemistry is still not completely understood. As this knowledge increases‚ winemakers are being helped to improve the quality of their wine

Food and Beverage 1. Description of organizational procedures for use of legal measurement of drinks and the importance of doing so. I was employed as a waiter at Co.Fi restaurant in Brooklyn. According to their policies and procedures I was not allow to serve alcohol to any person under the age of 23. I was required to ask customers for identification. Although the South African Liquor Act states that any person over the age of 18 may be served with alcohol‚ Co.Fi did not allow that. I

Fermentation is the process of controlling bacteria‚ yeast and moulds to modify food‚ producing a desired product. Fermentation occurs naturally in many different foods given the right conditions‚ and humans have intentionally made use of it for many thousands of years Fermentation can improve food so that: Tastes

be used to make beer It is an extremely old drink and has been made since before Roman times There are different types of beer. The different types are made by using different strains of the yeast Saccharomyces cerevisiae and by changing the fermentation process. Malting: Barley is soaked in water and spread out to germinate When shoots appear the barley is dried to stop further growth During the germination enzymes change starch in the grains to sugar. When getting heated the malt changes

The Extraction of Bio-ethanol from Apple (Malus domesticus) and Banana (Musa accuminata Colla) Peelings through the Process of Fermentation and Distillation Abstract Apple (Malus domesticus) and banana (Musa accuminata Colla) peelings are common household waste products. This study sought to extract bioethanol from these two peelings and to compare which sample can produce more bioethanol. About 400 grams of apple and banana peeling was obtained from the 1 kilogram bought from the supermarket

example of carbon cycling at local scale is in ruminants where the digestion of cellulose occurs through microbial activity. These cellulolytic microbes hydrolyze cellulose to disaccharide cellobiose and glucose. Glucose then undergoes bacterial fermentation producing volatile fatty acids‚ CO₂ and methane. Many vitamins are synthesized at this point and microbial cells also good protein source. The nitrogen cycle is the main reservoir for nitrogen is

Fermentation of sugar by the mold Aspergillus niger is the chief commercial source of the acid. It is added to some foods and beverages to produce pleasant acid flavor; It is also used in medicines‚ in making blueprint paper‚ in textile printing‚ and as a polishing agents for metals. Citric acid is the product of fermentation of numerous
